libalpm/package.c : add _alpm_pkgname_pkg_cmp function.

_alpm_pkgname_pkg_cmp(pkgname, pkg) returns true iff pkg's name is pkgname.
This is useful if you want to remove a package from pmpkg_t* list, and you
want to search for package name.

This allows cleaning the -Ru code a bit, by removing the need of a dummy
pkg.
